50 has the circular recess 5 to fit onto said anabove stated, the eccentric opening 5 in said hand-wheel 5, into which the concentric edge of the gear-rim 6 loosely extends, causes said gear-rim 6 to move, so that the internal teeth 6 thereon will be engaged continually with the teeth 4 on the gear 2 through any movement of the eccentric opening 5 in the handwheel 5, and it will be seen that by one revolution of the hand-wheel 5 all the teeth 4 on the gear 2 will have been engaged by the teeth 6 on the gear-rim 6, and if there are one or more teeth 6' than there are teeth 4 the movement of the gear-rim 6 will be advanced beyond its original position by the difference in number of teeth between teeth 4 and teeth 6'. An operation of a similar nature will take place between the teeth 7 on the pulley or roll 7 and the teeth 6 on the gear-rim 6 during the same revolution of the hand-wheel 5, and there being more teeth 7 than there are 6 they will be advanced or moved forward in the same direction around the teeth 6 as the teeth 6 are advanced around the teeth 4, and the movement of the take-up roll or pulley 7 independently of the shaft 1 for one revolution of the hand-wheel 5 and eccentric opening 5 therein will be equal to the combined advancement of the teeth 6 and 7, above referred to. The continued revolution of the hand-wheel 5 will cause the take-up roll 7 to revolve on the shaft 1 as desired.

The advantages of our take-up mechanism 7 will be readily appreciated by those skilled given to it by the hand-wheel 5, so that there will be no backward or forward movement.

It will be understood that the details of construction of our take-up mechanism may be varied somewhat from what is shown and described, if desired.

Having thus described our invention,what we claim as new, and desire to secure by Letters Patent, is-

1. A take-up mechanism for looms, &c., consisting of a flanged gear to be secured on a shaft, a pulley or roll to be loosely mounted on a shaft, and having internal gear-teeth on the edge thereof, a gear-rim extending loosely within said teeth, and having external gearteeth to mesh therewith, and internal gearteeth to mesh with the teeth on said flanged gear, and a hand-wheel loosely mounted on said flanged gear, and having an eccentric opening therein to receive the concentric portion of the gear-rim, substantially as shown and described.

2. The combination with a driven shaft, of a flanged gear fast thereon, a pulley or roll loosely mounted on said shaft, and having internal gear-teeth, a gear-rim having external gear-teeth to mesh therewith, and internal gear-teeth to mesh with the teeth on said flanged gear, and a hand wheel loosely mounted on said flanged gear, and having an eccentric opening therein, into which extends -the concentric portion of the gear-rim, and means for holding the several parts in place, substantially as shown and described.
